It's not like your always losing business from someone undercutting you, sometimes it's just people adding additional business to the economy. As a hypothetical (using totally made up prices) I go to look for Iron ingots, 10 stacks are listing 10,000g which is a price that I decide there is just no way I'm ever going to pay for whatever reason, and 1 stack is listed at 5k which I think is reasonable, the person selling at that price isn't stealing your business because I wasn't ever going to buy your product anyways. People seem to act like everytime they are undercut by a large amount that they are somehow losing a potential sale. Same w/ a 2 star item, if everyone values it at 500k, which i don't want to pay, and 1 person decides they are willing to take the cut for whatever reason, and sells it for 100k, I might buy it. I get my item, they get the money they wanted, you haven't lost a sale.
